I think it's not good to call too much because it can make it difficult for everyone to get to them, especially for outlander, at the moment it's pretty difficult to get to one of the agents.Whilst I don’t agree with bugging them so much... I don’t see how they can do anything with UCI. So what if they flag for calling too much, since when did that turn to a criteria for rejection. At most you meet a very petty and wicked officer that will decide to sit on your application cause you called too much... but I would like to believe that no IRCC official will be that wicked. Either way better than sorry though.
